Check on the IDL code contrib site sometime next week. I just
uploaded DLMs that add arbitrary precision floating point as well as
integer and rational types to IDL. These are wrappers on the MPFR and
GMP libraries, respectively. Caveat emptor, but I'll answer emails.
You will need to recompile if using something later than IDL 6.3.
Examples included.
